Chem Talk

 I just ran across Chem Talk, which has tutorials and experiments.  Take a look at Copper Crystals.  You’ll need copper II sulfate.  Copper II sulfate is called ‘blue stone’ and is a root killer.  Older hardware stores or agricultural stores still sell it by the pound.  (Here is another lab that uses copper sulfate, a single displacement reaction.  This lab uses the same materials but explores Stoichiometry, the math ratios in Chem.  You will want to use up the copper sulfate.). Now that I’m way off topic, Chem Talk has tutorials, like this one about Combined Gas Law.  Chem Talk is launching LiveLab this Fall.  I’ll keep posting resources for Chem as I encounter them.
